Abstract: A water activated inflator and a method of air deployment of a water activated inflatable device are provided. A gas cylinder opening device for opening a sealing mechanism of a gas cylinder is disposed at least partially within a housing and is movable between a cocked position and a fired position along a first axis having a first orientation relative to the housing. A tension mechanism provides tension acting along the first axis for moving the gas cylinder opening device from the cocked position to the fired position. A plunger is holding the gas cylinder opening mechanism in the cocked position. The plunger is disposed in the housing and movable between a first position and a second position along a second axis having a second different orientation relative to the housing. A water soluble element is holding the plunger in the first position. A first interacting surface of the gas cylinder opening device is disposed at a predetermined angle to the first axis.

Abstract: The present invention relates to a heavy payload parachute ground disconnecting device. The device comprises an actuator for keeping a holding mechanism in a locked position during a predetermined time interval and after elapse of the predetermined time interval for releasing the holding mechanism when a force acting on the actuator is below a predetermined threshold. A latch mechanism releases a link assembly connected to the payload when itself being released from the holding mechanism. In the holding position the latch mechanism transfers a predetermined portion of a payload force for acting on the actuator within an operational range of the same. The device is highly advantageous by providing a simple, yet highly flexible, design for numerous payload ranges.
